Arctic and red fox population responses to climate and …
2023年7月17日 · Arctic foxes (Vulpes lagopus), an ecologically important predator in the Arctic, may be impacted by changes in climate within the southern extent of their range. Warming temperatures and a longer growing season are mechanisms that predict further range expansion of southern species into the Arctic (Post et al. 2009).
Red foxes at their northern edge: competition with the Arctic fox …
2022年1月28日 · We studied competition between Arctic and red foxes, with a focus on interference competition, and winter movements of red foxes using satellite telemetry and den occupancy data from both species. We worked at Bylot Island (Nunavut) and Herschel Island (northern Yukon), two sites at the northern limit of the red fox’s range.
